Abstract
Pulse compression is a technique that plays an important role in various fields like radar, sonar and spread spectrum communication to achieve the high transmit energy of a long pulse while preserving the range resolution of a short pulse. In this paper a new method of design of mismatched filter to minimize the Peak sidelobe ratio (PSLR) in the pulse compressed waveform is discussed. The method used here is the differential evolution optimization technique. The performance of the filter is studied with different codes like binary barker and chaotic codes . Results show that significant reduction in Peak sidelobe ratio is obtained at the output of the mismatched filter.
